INTRODUCTION
The Concrete Repair Association first produced the “Method of Measurement for Concrete Repair” document in 1990. The document was compiled with the support of FeRFA (The Federation for the Repair and Protection of Structures) many of whose members are, like those of the Concrete Repair Association, involved in concrete repairs and associated specialist activities. The Concrete Repair Association was also represented on a working party of the Concrete Society to produce a comprehensive model specification document for patch repair to reinforced concrete, being an update of an earlier document, and this included a section on measurement of repairs and was first issued in 1991. The Concrete Repair Association and the Concrete Society took care to ensure that the principles of the methods of measurement were compatible so as to produce a uniform approach within the industry. The Association issued ‘User Notes’ within a ‘Revision and Addendum’ leaflet issued in October 1994. This has been appropriately incorporated into this current fully updated Second Edition of the main document, which also incorporates changes thought appropriate following useful feedback from users of the Method of Measurement. The method of measurement includes for such activities as provision of access, surface cleaning, testing, repair items, surface treatments, etc., and these are treated using principles common in other areas of building, civil and structural engineering. With reference specifically to the Repair items within the method of measurement:a) A single item will include work and materials to complete the repair, e.g. cutting the repair edges square, breaking out the existing concrete, cleaning and protection of reinforcement where exposed, applying the bonding coat and reinstating with mortar. Repairs are measured separately according to the orientation of the surface on which they occur, e.g. soffits of slabs are measured separately from vertical surface of walls; arrises of columns are measured separately from arrises of beams. Flat repairs are measured separately from those which contain an arris. Repairs are generally measured by number in bands of surface area and maximum depth. In the case of arrises they are measured by length or number in bands of girth and maximum depth. Patch repairs, as their name implies, are usually small individual items and the vast majority of repairs should fall into one of the specified area bands and enumerated. However, larger individual repairs are measured by area.

c) d)

e)

The sub-divisions into different orientations, repair types, areas and depth can lead to a large number of item descriptions. For instance, when fully using the various depth bands and the area bands and taking account of possible sub-divisions for vertical and horizontal surfaces and also for repair items to arrises, this can produce in excess of one hundred different items of repair. However, it has been found that the system is simple to operate and it is expected that in practice most projects will be covered by thirty or forty items in total. The specimen Bill of Quantities is in abbreviated form and is for guidance only. There is a space for those using the document to include their own detail notes on

the facing pages headed “User Notes”. The preamble item “Bill of Quantities” states that “Bill of Quantities shall fully describe and accurately represent the quantity and quality of works to be carried out”. In concrete repair contracts it is difficult to accurately quantify the amount of work at the time when the contract documents are being prepared. The depth and area of a particular concrete repair item cannot usually be determined until breaking out is complete. The bill of Quantities can therefore be regarded as approximate, the accuracy of the quantities depending upon the degree of initial survey and sampling and testing data available prior to production of the Bill of Quantities document. This should be made clear to all parties involved with the contract. To attempt to overcome some of the difficulties associated with this situation, where remeasurement is inevitable, this method of measurement itemises time related elements such as provision of access and site facilities. These can then be adjusted as necessary if the quantity of work should differ substantially from that shown in the documents, dependent upon the conditions of contract. If there are limitations on the amount of work which can be carried out at one time, resulting from, for example, the extent of scaffolding permitted, it may be necessary to sub-divide the bill to reflect the phasing of the work. To reflect the variation in cost with height above ground related to the time taken for the workforce and materials to get to the place where work is being carried out, particularly in the case of access by cradle, work can be sub-divided into height bands above ground. However, this can lead to a proliferation of different items and subdivision by height above ground needs to be considered on its merits for each case and only used in appropriate circumstances. There are other occasions when sub-division is appropriate, for example, in cases of reduced headroom or confined working space. The method of measurement is ideally suitable for use with computerised systems for surveys, bill of quantities production, schedule of rates pricing and re-measurement and valuation of completed works.

1e) In this case the area shall be measured as the sum of the areas on the individual faces. two horizontal and one vertical meeting as a common point. 1e and 1f. where repairs span more than one face of a member. 1a) b) If a repair to a beam or column includes two arrises it shall be measured as two separate repairs with the centre line of the common face taken as the dividing line between the two repairs.SECTION 3: NOTES ON REPAIR MEASUREMENT INCLUDING ILLUSTRATIONS
General Repair and Repairs to Arrises a) In general. The arris repair shall be taken as 450mm girth and the other repair shall be measured as a repair to a flat surface of the remaining area. Localised deeper areas which in total do not exceed 10% of the area shall not be taken into account when assessing the repair depth. the maximum depth shall be measured on the largest face and this depth used to categorise the repair. 1b) c) Repairs to flat surfaces which include an arris and which lie outside the maximum girth of 450mm shall also be measured as two repairs. (see fig. f) Repairs including two corners of a slab or balcony and the like involving five arrises shall be measured as two repairs with the centre line of the slab taken as the dividing line between repairs (see fig 1f) g) The depth categories are according to maximum depth of the repair measured perpendicular to the face of the member and taken within a substantial proportion of the repair area. 1d) e) An exception to this is repairs to corners of slabs or balconies and the like. (see fig. (see fig. For repair to corners of slabs of balconies and the like. repairs on flat surfaces do not include for the re-creation of an arris and repairs to arrises include for the re-creation of only one arris. Repairs measured in this category include for the re-creation of three arrises e. (see fig.g. (see fig. 1c) d) A similar approach shall be adopted if the repair covers two arrises when the repair would be measured as three separate repairs. Accidental overbreak shall not be included when assessing the depth of a repair. as in fig.
